National Library of Medicine Classification: A Scheme for the Shelf Arrangement of Books in a Field of Medicine and Its Related Sciences. Fourth Edition.

Wiggins, Emilie, Ed.

Outlined is the National Library of Medicine classification system for medicine and related sciences. In this system each preclinical science, such as human anatomy, biochemistry or pathology, and each medical subject, such as infectious diseases or pediatrics, receives a two-letter classification. Under each of these main headings numbered minor headings are found. For example, under human anatomy (QS) one finds general works (4), addresses, essays and lectures (9), and dictionaries and encyclopedias (13). This volume also gives a special classification scheme for nineteenth century publications and an index to the classification system. (BB)
